The DTV12V and SUB9V lines are monitored by the MCU. If the voltage corresponding to the number
of blinks is missing or shorted, the MCU shuts down the unit and blinks the Power LED. Reseat the connectors P3
and A3 and turn on the unit. If the shutdown persists, use a voltmeter to measure the voltage. If it is present, replace
the A board. If it is absent, use an ohmmeter to determine if there is a short to ground. When a short is detected,
disconnect the connector P3 or A3 to isolate the short to either the A or P board.
